Why does the oxygen flow rate decrease and the flow meter cannot be adjusted after using the oxygen concentrator for a period of time? How to solve this problem? _Baidu After using the oxygen concentrator for a period of time, the oxygen flow rate decreases and the flow meter cannot be adjusted. The main reasons are that the humidification cup is blocked, the oxygen tube is too thin, or the compressor cup is worn. This can be solved by cleaning the humidification cup, replacing the oxygen tube, or contacting after-sales maintenance for the compressor.
1. The reason for the decrease in flow rate of the oxygen concentrator is due to personal use issues, such as improper maintenance, blockage of the tubes in the humidification cup, and lack of oxygen supply. When the oxygen concentrator is working, the internal temperature is about 60 ℃, and the temperature difference caused by the contact of oxygen with water through the humidification cup can lead to the formation of scale after long-term use.
. When scale blocks the outlet of the humidification cup tube, the oxygen flow is obstructed, resulting in a decrease in flow rate. The purchased oxygen tube is thinner than the original oxygen tube with a standard inner diameter of 6.5-9mm. If an oxygen tube with a smaller inner diameter is used, it will limit the oxygen output and result in insufficient flow rate. The compressor of the oxygen concentrator has attenuation, severe wear on the skin bowl, and insufficient power, resulting in insufficient pressure. The compressor is the core component of the oxygen concentrator, and its skin bowl will wear out after long-term use, leading to a decrease in power, insufficient pressure, and ultimately affecting the oxygen o
2. Problem solution: For clogged humidification cups, clean them regularly: replace the filtered water every 3 days, soak the humidification cup in white vinegar for 15 minutes every 2 weeks, clean the scale inside the tube, and then pour out the white vinegar.
. Expand the air outlet: Use scissors to cut the front end of the humidification cup tube into a large hole to enhance oxygen circulation. Replacing the humidification cup: It is recommended to replace the humidification cup once a year to avoid blockage caused by long-term use. Purchase oxygen tubes with a standard inner diameter (6.5-9mm) and reliable quality for oxygen tubes that are too thin, and avoid using inferior tubes (such as products with strong odor, thin diameter, high hardness, and insufficient length). If the oxygen concentrator is within the warranty period and the compressor malfunctions (such as being unable to operate) due to the wear of the compressor skin silver blocking bowl, you can contact after-sales maintenance; But compressor attenuation (insufficient power) is usually not covered by warranty. Before purchasing, it is necessary to confirm the compressor brand (such as Thomas from the United States, Guangshun from China, etc.) and quality, and prioritize the selection of products with high reliability.The 2.3L oxygen concentrator is not producing oxygen and the flow valve cannot be adjusted.
